To atl whom it mayconcermn Be it known that I, JOHN W. NUNAMAKER, a citizen ofthe United States, residing at Chicago, in the county of Cook and State of Illinols, have invented certain new and useful and Com uting en 1n for use in stores, factories, and other large esworkman tablishments where it isnecessary to compute the time of the employees.

This invention pertains to an improved apparatus by;l means of which each individual as a specifictiming device, which bein operated at the b egmning and end of any etermined interval of time will com'- l ing and will provide ,means of gua against errrors and inaccuracies by sounding ready for operation. y

and improved form, `the arrangement ofv which will facilitate the operation of com tan alarm, so that an announcement is made of the operation of the lever. l

To this end 'my'invention consists of eer-1 tain details of 4constructions and combination of parts, all as hereinafter more fully setforth andcllaimed.l

' My invention further comprises means for taking an impression from the computingwheels at an time it is desired to know how long any or a l of the employees have worked.

Referring to the figures in which the invention is shown more 1n detail, I will first describe the computing mechanism and then explain its connection with and operation by the clock mechanism.

Referring to the drawings, A, Figi 1 ,is a suitable case within which is inclose the principal mechanism of the machine. The front and back kof this case are hinged together, so that it may be opened at any time for inspecv y v 13 are details of a cam-disk. Fig. 14 is a de f My invention relates to a time recordingV land computing mechanism, and is designe ig. 16a is a plan view of the hours,l or at any intermediate time, if it is so s ond with those pieces b, Fi s.

tion orto take an impression of the time computed. The case A is provided a`t the top thereof `with two dials A and U and at the bottom with the opening A2, inside of which the employees numbers and the levers for Fig. 2, designates as a ywhole thev inner frame of' the recording mechanism. This ,frame is divided umns b2 b3 b", Fig. 7, in this instance three sec-` into vertical sections or coltions being shown; but it is obvious that a reater or lesser number could be used, this being determined by the number of employees registerin Each of these vertical sections shown in t e drawings contains complete registering mechanism for eighteen employees, the device here illustrated having a total capacity of fift -four time-computing mechanisms. .In co umns a a (L2, Fig. 7, at the right of each of these vertical sections, are arranged consecutively the number by which each employee is registered. These numbers correshown in the columns A3.

ach number has se arate andindependent computing-wheels, tihree in number, c c c2, Fig. 10, and a descri tion of one set will sufe fice for all of them. fhe frame B, containing this -recording and computing mechanism, comprises a number of sections or frame- 9, 10, and 11. These sections are made o sheet metal, having perforatioiis c3, through which the wheel-arbor's ass. At intervals upon each. longitudine. edge of these sections or frame-pieces b are lips c4,

bent downwardlyT at right angles to the topl thereof to form partitions between the sections when they are assembled one above the other, as shown more clearly in Fi 9. Each of these sections or frame-pieces in a com'- `puting mechanism of this ca acity has three sets of five erforations c3, ig. 10, through which pass t earborsddd2d3d,Fig,11,u on which are mounted the computin -whee s c, c', and c2 and pinions ce and c7. ach set of numbering or com uting wheels com rises what I shall terni orthe purpose of istinguishing them a units-wheel c, an hourwheel c', and a computin -wheel c2. Motion is transmitted to these w eels through the trains of gears C, Fig. 8, which receives motion through arbor I, havin connection with the clock mechanism, whic in turn is actu ated through mechanism hereinafter explained. As the wheels are assembled in the recordingY and computing mechanism the minute-wheels c are mounted upon the arbor d, the pinions ce upon arbor d', the hourwheels c upon arbor d2, the pinions c7 upon arbor d3, and the computing-wheels c2 upon arbor d4. Each of the numbering-wheels c c c2 is provided upon its periphery with impression-numbers from l to 9, spaced equidistantly apart. tioned upon the wheels so that they may be read horizontally, as shown in Figs. 7 C 11, and 16. Arbors G G G2, one for each set of recording-wheels, are vertically disposed in the frame B of the recording mechanism. These arbors are alike, so that a description of one will suflice for all three. The arbors G G G2 are provided at intervals corresponding with the sets of numbering-wheels in the col,- umn witha notch or recess g, Fig. 15. Mounted upon the arbors G G Gz are a'series of The numbers are posil gear-wheels 9', corresponding in number with the number of setsof computing-.wheels in thatI column. Each of these gearwheels g is provided with a split sleeve g2, Fig. 15, the outer end of which is bent slightly inward and adapted to fit into the notches g on the arbor. The gears are thus held into frictional engagement with the arbor and turn with it in the operation of the computin mechanism.

Movably secured to each o the framepieces b are the lever-arms F, one for each set of computing-wheels. Mounted u on each of the lever-arms is a pair of gear-w eels f f adapted to mesh with each other and when placed into operating position to mesh with the gears g upon the arbore G G Gz to trans mit motionl to the 'computing-wheels in a manner hereinafter described. The arms F carry the operating-levers F" (Shown in Fi s. 1, 7b, and 8.) A projectionf2 is ro vi ed at what the arm F. Dis `osed at suitable positions in the frame B wit relation to the movement of the arms F are vertical rods F2, partially compassing which is av sheet-metal strip f3, Fig. 9`,having an outward1y-bent Harige. The strip f3 is held in place upon the rod Fc by being clamped tightly thereon, so that a movement of one will move the other. -The lower end of this rod rests vin an aperture in the frame B. The upper end is provided with a small crank-arm 4, Fig. 6.

Extending horizontal y across the top of V4the. frame B is a bell-rod H, Fi 6, provided at intervals with apertures a apted to receive the free end of the crank-arm At each end of the bell-rod H is provide an offset h. A bell-wire h is ositioned in the case sothat it rests within t is offset h and is actuated at eachmovement of the bell-rod H to strike one or the other of the bells H H2 'with one of the hammers h ha. Thus as an employee who is about to start his time moves the lever F corresponding to his number to the left he has brought the projection f2 on the lever-arm into contact with the flange f3, which has in turn, through the crank-arm f, moved the bell-rod H a sufliioo I shall term'the elbow of A cient distance to actuate the wire h and ring one of the bells, which sounds an alarm, enablin the person in charge, without observing te clock, to tell h ow many employees are registering.

Referring now to the assembling and operation of the computing-wheels, as before explained, they have the numbers positioned vertically across the peripheral face thereof. The units-wheel c, ypositioned uponthe arbor d, is provided with a gear 'i u on the under face thereof, land the teeth o this gear kare adapted to mesh with those upon gear f' when gear f is in mesh withgear g. There are ten teeth in this gear fi, one corresponding to each figure upon the periphery of thewheel. Upon the other face of the wheel is a small depression i', upon either side of which is an upwardly-extending tooth. The pinion c", mounted upon arbor di', has a sleeve if", the edge of which rests upon one of the framepieces b to elevate the teeth of said pinion, so that they will mesh with the teeth upon the computing-wheels. The teeth of this pinion are of two widths, as shown in Fig. 7 d, and are disposedal-ternately, one wide tooth i3 and one narrow tooth i4, for a ur ose hereinafter described. The hour-w ee c', which is mounted upon the arbor d, is the same size as the units-wheel with the ten ii res positioned vertically across the erip eral face thereof. The upper edge of t e wheel (as it is positioned upon the arbor) is provided with teeth, in this instance twenty in number, two teeth corresponding with each ii ure upon the periphery of the wheel. The' ower edge of this hour-wheel has two proecting teethj,

one u on either side of a smal depression 1n the e ge of the wheel.

A pinion c mounted 'upon arbor d3, having alternately a wide and anarrow tooth, the same as pinion c", previously described, meshes with the vteeth j u onv hour-wheel c in the operation thereof, an at certain predetermined intervals transmits motion to the computing wheels c. The com uting-wheel c2, mounted upon' arbor d4, iso the same size as the minute and hour wheels and has the figures thereon verticall disposed across thevperipheral face thereo The lower edge of the wheel is provided with teeth. (Shown in detail in Fi s. 16 and 16a.) There are two teeth for every ure upon the periphery of the wheel. As s own in Fig.

` 16", there is a blank tooth jlso positioned upon the wheel that this tooth reachesthe pinion c1 in the revolution of the computingwheel when the cipher on the said wheel has reached the forward position, or the position from which the impression is taken. The time-recording mechanism has now reached the limit of its recording capacity and is locked in this position until reset, which is done by mechanism hereinafter described.

Referring now to the clok mechanism, I will explain the connection and operation of the same in conjunction with my time-computin device.

.In igs. 3, 4, and 4a I have shown the movement of an eight-day clock with what changes in its construction I have made in utilizing itto operate the arbor I, which transmits motion yto the train of gears C, operating .the time-wheels, extends upwardly to the clock mechanism, and has u on the end thereof a bevel-gear J, which mes es with another bevel-gear J. The bevel-gear J has a pinion J2 mounted u on shaft J3, and this pinion meshes with t e striking-wheel K of the clock. In utilizing the main wheel of the striking-train to reset the computing-wheels I have removed the usual, pawl and ratchet from the wheel K and have placed it upon the second wheel t, so that WheelK will move 'in either direction.

This wheel tis mounted upon an arbor journaled within the frame vo the clock-movement and is operated by a pinion t', journaled upon the same arbor and meshing with the gears upon wheelK. The arbor K extends upwardly to the clock mechanism and has at the top thereof a gear k, which is connected, through atrain of gears, to the hour-wheel K2. Through this arbor K and its coperative mechanism the operation of the computing-wheels is regulated'. U on the hour-wheel spindle k is mounted w at I shall term a double cam-wheel k3. (Shown in detail in Figs. 12 lto 13.), These cam-wheels telescope each other upon the hour-Wheel spindle, and by moving one upon o the other the extent of the cam-surface can be regulated a greater or less distance, as desired, according to the number of hours it is desired to keep the recordingmechanism out of operation. These cam-wheels are kept turning with the hour-wheel, which through coperative mechanism is operating the' arbor K. I have changed the construction of the striking-rod Z of the clock mechanism, andv by utilizing the striking train of gears for transmitting motion to the recording- Wheels through arbor I. I have extended the release-rod Z, Whichissecured at .one end to an arbor l', which is journaled within the frame of the clock mechanism outside the frame l2 of the clock-movement, and extend the same a sufficient distance that it will contact with the periphery of the cam-wheels k3. The cam-wheels k3 being positioned upon and IIO moving with the hour-wheel spindle, it'will ployees hours of service extend for illustration we will say from eight a. m. until six p. m. and the computing mechanism is set to operate while the employees are at work, the cams projecting upon these wheels are turned so that they represent one-sixth of the circumferential surface of the wheel, the other five-sixths of this surface representing the number of hours which the computing mechanism is to be in o eration. When the computing mechanism is started, (by an' operation to be hereinafter explained,) the rod Z is in contact with the surface of the camwheel at the point and during the time lapsing from ei ht a. m. until six p. m. the cam-wheels will have turned until the cam projection k comes in contact with rod Z, when it is automatically raised, (by mechanism hereinafter explained,) and this operation locks the reading and computing mechanism. Mounted upon the'minute --spindle near the rear frame of the clock-movement is the wheel Z3, Fig. 4, having ten teeth upon the periphery thereof corresponding in point of time to one-tenth of an hour. Thls wheel Z3 is operated the same as the ordinary strikingwheel of a clock; but b the uniform arrangement of the ten teet upon the periphery thereof it is unlatched through the operation of the catch-rod Z at intervals of every six minutes. Each time the catch-rod l* is actuated and moved out of eontact with one of the teeth upon wheel Z3 the said wheel moves the space of one tooth, and by so doing the arbor I has been actuated a corresponding distance, and through the train of gears in contact therewith it has transmitted this movement to the units-wheel c and caused it to revolve the space of one figure thereon. Thisoperation is of course repeated every six minutes during the time the computing mechanism is in operation. We will assume, for illustration, that all of the recording-wheels are set at zero and the recording mechanism is ready for operation. wheel c, as above explained, being moved the space of one gure for every six minutes, it

. requires just one hours time to make a complete revolution. This wheel is so positioned upon. an arbor d that at the last movement in the hour the cipher upon the periphery of the wheel is presented in impression position and the depression i', with the two teeth upon the upper edge of this wheel, has come into mesh with the tooth upon the pinion c, which meshes with the teeth upon the hour-wheel c 'and has moved the said hour-wheel the space of two teeth, bringinginto impression position the figure 1, which records the first hours time. The minute-wheel c is again being revolved at the rate of one figure every six minutes until it makes the second complete revolution, when through the pinion c's it will actuate the hour-wheel and Vit is moved Vthe s ace of two-.teeth and presents the gure 2, thus recording two hours time. This o eration is repeated until the hour-whee has made a complete revolution and has recorded ten hours time, when through the operation of the two teeth upon the under face of said wheel coming into contact with the pinion c7, the teeth of which pinion are in mesh'with the teeth upon the computing-wheel c2, the said computing-wheel is moved the space of The 'two teeth, bringing into impression position the figure 1 on said wheel, recording thereby ten hours7 of time. his operation of recording is repeated until the computing-wheel has made one complete revolution. The hourwheel moves the space of one figure for eve complete revolution of the minute-whee and the computing-wheel movesthe space of one figure for ever complete revolution of the hour-wheel. en the computin -Wheel has made one com lete revolution, it as re istered the limit otpits capacity and the blan tooth j has come'into contact with the pinion c7 and is locked into this osition until the mechanism is reset,y Whic is done by mechanism hereinafter explained.

Referring more particularly to Figs. 6 and 7, the arbor K has mounted thereon a series of cam-wheels m, there being one cam-wheel for veach column of recording-wheels. Pivotally secured .to the top plate of the frame B are the lever -`arms m m m, each one held in normal position by a spring n n n.A

These cam-Wheels are so adjusted that the projection thereof comes in contact with the arm of one of these levers m', m2, or fm at the particular hour the employees registering upon the time-wheels in one column leave their work for one hours time, more or less, at noon. For illustration, referring to Fig. 6, the lever-arm mf regulates the operation of the recording-wheels in the first column b. If the noon hour of the employees registering in this column begins at'11z30 a. m., the cam- Wheel m, Contactin with the lever-arm m is so adjusted vupon t e arbor K thatl the cam projection contacts with the lever arm m at that hour. This contact of the lever m with the projection u on the cam-wheel tiltsthe lower arm of the ever o to the position shown in dotted lines, throwing the gears O out of mesh with intermediate wheel g', thereby disconnecting the operation'of the time-computing mechanism in that column until the cam projection has assed beyond the leverarm m', when it Wil resume its-normal osition and the recording-wheels are place in operation again. To throw the recording .mechanism out of operation for longer periods of time, I provide a lever P, secured at its fulcrum-point 1p to the casing A. The lower arm p of this ever extends downwardl through an elongated slot p in the bell-rod The upper arm p3 extends upwardly to a point enabling it to ass under the shoulder Figs. 3 and 4, of t e rod Z.

Mounted upon the arbor K is a cam-wheel R. This wheel R is positioned upon the arbor K', so that at the hour the employees stop work the cam projection n upon said wheel will have reached the small arm p, secured to lever-arm p. By the contact with the cam the-lower arm p of lever P- is moved a suiiicient distance to throw the upper arm p3 under the shoulder 1' of the rod Z,

IOO

IIO

holding the s aid rod away from the cam-wheels k3 and locking the computin "mechanism, The lever p3 will hold the rod in this outof-contact position until one of the levers F has been operated. The first y, em loyee to register moves one of the levrs F corres onding to his number to recording osition. his operation moves the bell-rod to the left, as shown in Fig. 6, carrying with it the lower arm p of lever P, which extends lthrough the slot p2 in the bell-rod H. This movement of lever p has caused the lever p3 to move in the opposite direction and release the rod l, which drops to normal position and sets'the computing mechanism into operation. When it is desired to know the number of hours the employees or any of them have worked, an impression is taken upon asheet of aper placed over the computing-wheels in the ol owing manner: U on the top of the frame B is secured a paperolding device. (Shown in cross-section in Fig. 7 Q is a metal strip extendin across the top of the frame B and is pivotalIy secured thereto at each end thereof. A spring holds the bent edge q of the metal strip in normal osition firmly against the top section ofthe fiiame B. When it is desired to take an impression of the time computed upon the recording-wheels, a sheet of plain paper and a carbon-sheet are secured at one end under the bent edge g of the metal strip Q, as shown in`cross-sect1on in Fig. 7 "1. The sheets of paper Iso hung in the paperholder cover the front of the computingwheels, as shown in Fig. 7 with the paper partially torn away to show some ofthe computing wheels. As previously ex lained, ythe figures upon the periphery of t e computing-Wheels are in raised position thereon, and in operation the figures directly in front represent the time computed. With the paperin the position just explained an attendant passes a roller (shown in Figs. 17 and 17a) down over the pa er and presses it in contact with the num ers on the wheels, and by means of -the carbon-sheet an impressionof the time recorded on said wheels is made upon the plain paper. The attendant raises the holding-strip Q and removes the paper with the record of all lthe employees impressed thereon. n

In Fig. 18 I have shown an impressionsheet which, it will be observed, shows the number of each employee and the time in hours and the fraction of an hour which each one has been working. The first column of .figures at the left indicates the employees number and the next three columns the time `computed by eachof the three recording' wheels and in this impression-sheet indicates that No. 1 has worked one hour and twotenths of an hour, as have all the rest in that column. Those registering inthe second column, beginning with No. 19, have eachI worked thirty-four and five-tenths of an as in Fig. 7.)

hour. Those registering in the third column, beginning with No. 37, have each Worked sixty-seven hours and eight-tenths of an hour. Upon the impression-sheet here illustrated it is shown that those registering in each column have all worked the same number of hours. It is obvious, however, that each employee might have been registered a different length of time, if the device was in use in a place wherethe employees were at work at irregular intervals.

When the machine has recorded its full capacity of ninety-nine hours or when for any other reason it is desired to reset the computing mechanism at zero, it is done by winding the strikin -sprin S of the clock in the usual manner, W ich, t rou h the medium of the bevel-gears, revolves t e arbor I. The arbor I has upon its lower end a gear corresponding in size and number of teeth with the fears 4 mounted upon arbor G. The arbors Iband G are joined together at the top of the frame B in any desired manner. The gear upon the arbor I corresponding with that shown at s,

Fig. 6, meshes with a train of gears S (shown in Fig. 6) and transmits the motion thereof to each of the arbors G G G2 to reset therecording-Wheels to zero osition. When the recording mechanism 1s in operation, the

wheels are turned from left to right. (Viewed When the device has reached the limit of'its registering capacity, the coniputing-wheels c2 are locked from further movement in that direction by means of the blank tooth (shown in Fig. 16") coming in contact with the pinion c7. This wheel makes but one revolution in recording the ninetynine hours, and to reset the mechanism tol zero the wheels are turned in opposite direction one revolution to original position. In

the operation of winding the striking-spring of the clock it reverses the movement transmitted through the arbor I, and the train of gears meshing with the gear upon said arbor to the arbors G G G2 resetting the computing mechanism. The wheels c c c2 are turned in this reverse movement until the blank tooth j has again come in contact with the pinion c7, when it is locked in that position,

and that set of wheels is in zero position again. When some of the recording-wheels have not registered their full capacity, they are of course reversed to zero position sooner than those that have recorded ninety-nine hours. The gear-Wheels upon the arbors G G G2 being positioned thereon, as illustrated in Fig. 15, they are held to the arbor by friction and turn with it until. any particular set of recording-wheels receiving motion through one of these gears has reached zeroposition,

it no longer moves .with the arbor,but remains at rest, the arborrevolving within the split sleeve g2 until all of the recording-wheels are reset to zero position, when the striking-train is Wound up.

The dial U is mounted upon the hour-wheel spindle and revolves with the cam-Wheels 7c3. A hand u indicates upon said dial the hour at which the computing mechanism is to be set into operation. The cam-Wheels k3 are so positioned upon the hour-Wheel spindle that l the said Wheels have revolved so that the ees' are Working' ten hours a day and projections k* have passed beyond the rod l and said rod comes in contact with the Wheels at the point when thecomputing-wheels are started into operation. l

In the foregoing description' I have explained the operation ofthe mechanism computing the time while the employees were en;

aged at work. In practice -it has been ound 1n some instances more desirable to record the time yvhen the employees are not at Work. For illustration, if all of the employare promptly on time each day their full week is counted as sixty hours, and the record-sheet IWill show the cipher in impression osition upon each Wheel,indicatin that eac one of the employees had served 's full time. If, however, some of themV are late or absent at any time, their recording mechanism being in operation, the length of time of such absence is recorded against them and deducted from the full Week of sixty hours. As is obvious, the operation of the computingvmechanism would be exactly the same in either case, except that the levers F.- Would be moved in the op osite direction.` v' I have described quite in detail the construction of the mechanism employed herein; but it is obvious that any of the details thereof might be changed without departing from the spirit of my, invention,` which'consists,

ical equivalents of any o essentially, in providing .time -computing mechanisms having a plurality of com uting.

I have herein shown and described a mech' anism having a recording capacity of ninetynine hours but I do not Wish to be limited to that number of hours, as it is obvious that by adding a greater number of computingwheels the capacity of the machine might be increased to any extent desired.
